Conditioning Composition

ABSTRACT

A conditioning composition is free of talc and includes tapioca starch, optionally potato starch, optionally corn starch, at least one anionic surfactant, and optionally at least one amphoteric surfactant, which may be described as a core particle. The conditioning composition may include, or be free of, a coating disposed about at least a portion of the core particle and having a compound chosen from cellulose polymers, anionic or cationic polymers, vinyl polymers, natural polymers, polysaccharides, copolymers thereof, and combinations thereof. The conditioning composition includes from about 0 to about 25 percent by weight of liquid, has a pH of from about 3.5 to about 5 when mixed with water at about 10 wt % and produces a flash foam of less than about 10 ml when contacted with water at a temperature of about 26 to about 30° C. degrees.

FIELD OF THE INVENTION

The present disclosure generally relates to a conditioning composition that is free of talc and includes tapioca starch, optionally potato starch, optionally corn starch, at least one anionic surfactant, and optionally at least one amphoteric surfactant.

BACKGROUND OF THE INVENTION

Many personal care products are formulated to provide consumers with effective conditioning as well as additional benefits. However, traditional conditioning products present various challenges. Most of these products are liquid based, can be messy, difficult to dose properly and tend to leak during transport. For example, many include about 85-90 wt. % water and lose efficacy and integrity in water solutions over time. This loss of performance is due to incompatibility of reactions that are not visible, thus consumers do not receive the necessary fresh benefits of the product. The early development of waterless products in the market have been as aerosols that are delivered as mousse leave-on products on hair. These forms of hair care products are convenient for traveling and are effective for a few hours, but they tend to leave the hair coated with undesirable effects of oil, limpness and dullness. Furthermore, these conventional products are sold in large packaging and volumes, which commits the consumer to a specific fragrance or product benefit for an extended period. These products are of a single pH range which changes in time and can damage hair and are not suitable for all hair types. Furthermore, these products require high energy and heating to 70-80° C. for emulsification for 35-60 minutes. Very often initial or final viscosities are inconsistent and unpredictable with discoloration which is problematic because viscosity has thermodynamic effects on thickening and thinning products.

Unit dose products have been accepted in the laundry and dishwashing fields because these products have advantages of being convenient, easy to dispense, and provide the opportunity to customize each wash for the benefits the consumer is seeking. Similar advantages are desired by consumers in the personal care space. For example, cosmetic articles intended to be used once to cleanse the skin or hair are well known for their practical benefits. Disposable wipes impregnated with a liquid cosmetic formulation are suitable for single use but requires disposal of the nonwoven sheet. Travel sized and single use toiletries are available but demand the use of more packaging and are not environmentally friendly. Single use bar soaps and other forms of single use soap exist but utilize raw materials that consumers do not want in their products such as talc.

Consumer demand for natural beauty products has been a growing trend for years and has led to the rise of “free from” advertisements on the front of various products. Key attributes in demand are biodegradable and sustainable raw materials, as well as products “free from” sulfates, alcohol, parabens, talc and other things consumers perceive as less than beneficial. Formulating to meet all these desired demands is technically difficult and limits the choice of raw materials available to the formulator.

In hair conditioners, silicones such as cyclomethicones, dimethicones, amino silicones are used as the primary conditioners in combination with or without quaternary ammonium compounds. Formulation with silicones D4, D5 and D6 have recently been reduced in hair conditioners. Emulsification of silicones systems require emulsifier/surfactant and a heating temperature of about 70-80° C. for at least 30-60 minutes along with cooling. Accelerated or thermodynamic aging of raw materials in the product is not avoided. Furthermore, such formulations tend to lack production efficiency and down time.

There are some products on the market that are environmentally friendly and consumer friendly, but still have additional drawbacks. Loose anhydrous powder, such as that disclosed in WO 2019/001940, does not solve the problems of single use, customization, or remaining free from talc. Foaming conditioning powders on the market are also loose powders, which are messy and difficult for consumers to dose. Still other products crumble during shipping thereby forming a coarse and gritty texture that is not commercially desirable. Moreover, these types of compositions use propylene glycol and not water thus reducing commercial desire among consumers and also tend to have a rough hand feel.

Accordingly, there remains an opportunity for improvement. Furthermore, other desirable features and characteristics of the present disclosure will become apparent from the subsequent detailed description of the disclosure and the appended claims, taken in conjunction with the accompanying drawings and this background of the disclosure.

BRIEF SUMMARY OF THE INVENTION

This disclosure provides an encapsulated conditioning composition that is free of talc and includes a core particle that is a powder. The core particle includes tapioca starch, optionally potato starch, optionally corn starch, at least one anionic surfactant, and optionally at least one amphoteric surfactant. The encapsulated conditioning composition also includes a coating disposed about at least a portion of the core particle and comprising a compound chosen from cellulose polymers, anionic or cationic polymers, vinyl polymers, natural polymers, polysaccharides, copolymers thereof, and combinations thereof The encapsulated conditioning composition includes from about 0 to about 25 percent by weight of liquid, has a pH of from about 3.5 to about 5 when mixed with water at about 10 wt % and produces a flash foam of less than about 10 ml when contacted with water at a temperature of about 26 to about 30° C.

This disclosure also provides a non-encapsulated conditioning composition that is a powder, is free of talc, and includes: tapioca starch, optionally potato starch, optionally corn starch, at least one anionic surfactant, and optionally at least one amphoteric surfactant. In this embodiment, the non-encapsulated conditioning composition includes from about 0 to about 18 percent by weight of liquid, has a pH of from about 3.5 to about 5 when mixed with water at about 10 wt % and produces a flash foam of less than about 10 ml when contacted with water at a temperature of about 26 to about 30° C.

This disclosure even further provides a conditioning composition that can be encapsulated or non-encapsulated and may or may not include a coating disposed thereon. This conditioning composition is free of talc and includes a powder including tapioca starch present in an amount of from about 60 to about 65 weight percent based on a total weight of the powder, potato starch present in an amount of from about 3 to about 5 weight percent based on a total weight of the powder, corn starch present in an amount of from about 4 to about 6 weight percent based on a total weight of the powder, at least one anionic surfactant that is a glutamate and that is present in an amount of from about 2 to about 4 weight percent based on a total weight of the powder, and at least one amphoteric surfactant that is a betaine and that is present in an amount of from about 3 to about 5 weight percent based on a total weight of the powder. The powder includes from about 0 to about 5 percent by weight of liquid, has a pH of from about 3.80 to about 4.80 when mixed with water at about 10 wt % and has a viscosity when dissolved as 10 wt % in about 100 mL water of from about 12,000 to about 20,000 cps as determined using a Brookfield Gel Timer DV2T Viscometer, RV, Spindle #6, at about 6 rpm for about 60 seconds at about 28° C. Moreover, the powder produces a flash foam of less than about 10 ml when contacted with water at a temperature of about 26 to about 30° C.

This composition is surprisingly advantageous as it readily disintegrates and provides little to no flash foam which can be then used to condition the skin and hair. The conditioning composition is also gentle, mild and moisturizing to the skin. Moreover, the composition is free from talc. Talc is used in powder formulations to contribute slip and a silky skin feel. In the instant composition, the tapioca starch, in optional combination with the other starches, surprisingly provides the desired skin feel without the need for talc.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description is merely exemplary in nature and is not intended to limit the encapsulated conditioning composition. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.

Embodiments of the present disclosure are generally directed to a conditioning composition and methods for fabricating the same. For the sake of brevity, conventional techniques related to conditioning compositions may not be described in detail herein. Moreover, the various tasks and process steps described herein may be incorporated into a more comprehensive procedure or process having additional steps or functionality not described in detail herein. In particular, various steps in the manufacture of conditioning compositions are well-known and so, in the interest of brevity, many conventional steps will only be mentioned briefly herein or will be omitted entirely without providing the well-known process details.

In one embodiment, this disclosure provides an encapsulated conditioning composition that is free of talc and includes a core particle that is a powder. The core particle includes tapioca starch, optionally potato starch, optionally corn starch, at least one anionic surfactant, and optionally at least one amphoteric surfactant. The encapsulated conditioning composition also includes a coating disposed about at least a portion of the core particle and comprising a compound chosen from cellulose polymers, anionic or cationic polymers, vinyl polymers, natural polymers, polysaccharides, copolymers thereof, and combinations thereof. The conditioning composition includes from about 0 to about 25 percent by weight of liquid, has a pH of from about 3.5 to about 5 when mixed with water at about 10 wt % and produces a flash foam of less than about 10 ml when contacted with water at a temperature of about 26 to about 30° C. In various non-limiting embodiments, it is contemplated that all values and ranges of values, both whole and fractional, between and including the aforementioned values, can be utilized herein.

In another embodiment, this disclosure also provides a non-encapsulated conditioning composition that is a powder, is free of talc, and includes: tapioca starch, optionally potato starch, optionally corn starch, at least one anionic surfactant, and optionally at least one amphoteric surfactant. In this embodiment, the conditioning composition includes from about 0 to about 18 percent by weight of liquid, has a pH of from about 3.5 to about 5 when mixed with water at about 10 wt % and produces a flash foam of less than about 10 ml when contacted with water at a temperature of about 26 to about 30° C. This non-encapsulated conditioning composition may be a free-flowing powder or may be pressed into a shape, such as a cube, as further described below. In various non-limiting embodiments, it is contemplated that all values and ranges of values, both whole and fractional, between and including the aforementioned values, can be utilized herein.

This disclosure even further provides a conditioning composition that can be encapsulated or non-encapsulated. This conditioning composition is free of talc and includes a powder including tapioca starch present in an amount of from about 60 to about 65 weight percent based on a total weight of the powder, potato starch present in an amount of from about 3 to about 5 weight percent based on a total weight of the powder, corn starch present in an amount of from about 4 to about 6 weight percent based on a total weight of the powder, at least one anionic surfactant that is a glutamate and that is present in an amount of from about 2 to about 4 weight percent based on a total weight of the powder, and at least one amphoteric surfactant that is a betaine and that is present in an amount of from about 3 to about 5 weight percent based on a total weight of the powder. The powder includes from about 0 to about 5 percent by weight of liquid, has a pH of from about 3.80 to about 4.80 when mixed with water at about 10 wt % and has a viscosity when dissolved as 10 wt % in about 100 mL water of from about 12,000 to about 20,000 cps as determined using a Brookfield Gel Timer DV2T Viscometer, RV, Spindle #6, at about 6 rpm for about 60 seconds at about 28° C. Moreover, the powder produces a flash foam of less than about 10 ml when contacted with water at a temperature of about 26 to about 30° C. In various non-limiting embodiments, it is contemplated that all values and ranges of values, both whole and fractional, between and including the aforementioned values, can be utilized herein.

It is contemplated that when describing individual components of the conditioning composition any of the weight percents described below may be based on a weight of the conditioning composition as a whole or on a weight of the core particle as a whole (not including the weight of the optional coating) or on a weight of the entire encapsulated or non-encapsulated composition. Similarly, when any component (not including the optional coating) is described as being part of, or included in, the conditioning composition, those of skill in the art will recognize that this may also mean that the component is part of the core particle itself.

The conditioning compositions disclosed are useful in conditioning the skin, body, and/or hair, while remaining gentle and moisturizing. In one embodiment, the combination of potato and tapioca starch with the coating can provide a pressed powder with sufficient strength and rigidity to withstand packaging and shipping, but the product is soft enough to crush in the consumer's hand. The formulation is mild and gentle, moisturizing, naturally based and environmentally friendly. Alternatively, the combination of the potato, tapioca, and corn starches can also provide similar characteristics. Even further, any one of the starches alone can be used.

In one embodiment, as shown in FIG. 1 , this disclosure provides the encapsulated conditioning composition (20) (hereinafter referred to as an “encapsulated composition”). The encapsulated composition (20) includes a core particle (22), as also shown in FIGS. 2-5 . The core particle (22) is typically a solid but may be gel-like. Alternatively, the core particle (22) may have both solid portions and gel-like portions. In one embodiment, the core particle (22) is a tablet, as shown, for example, in FIGS. 1-3 . In other embodiment, the core particle (22) is a capsule or caplet, as shown, for example, in FIGS. 4-5 . In another embodiments, not shown in the Figures, the core particle is a cube. In still other embodiments, the core particle (22) is selected from the group of briquettes, pills, pellets, bricks, sachets, and combinations thereof. In one embodiment, the core particle (22) has a coin shape or a compressed cylindrical shape. In one embodiment, the core particle (22) is further defined as a “massive body” which, as is known in the art, refers to a solid shape (typically a porous solid shape) that includes a mixture of particulates. The particulates may be particulates of any of the components described herein. The core particle may be described as a plurality of particles of crushed powder. For example, any one or more of the components may be combined to form a shape (shaped body), e.g. in a mold. The shaped body may then be coated with a coating (24), or be free of the coating (24), which may also be referred to as an encapsulant or protective layer, as described in greater detail below. Throughout this disclosure, it is contemplated that the terminology “core particle” may also refer to the non-encapsulated composition, a free-flowing powder, etc. in various non-limiting embodiments.

The core particle (22) or composition, regardless of whether it is encapsulated or non-encapsulated, is not limited in shape, size, or mass. In various embodiments, the core particle (22) has a weight of from about 0.01 to about 20, about 0.05 to about 20, about 0.1 to about 20, about 0.5 to about 20, about 1 to about 19.5, about 1.5 to about 19, about 2 to about 18.5, about 2.5 to about 18, about 3 to about 17.5, about 3.5 to about 17, about 4 to about 16.5, about 4.5 to about 16, about 5 to about 15.5, about 5.5 to about 15, about 6 to about 14.5, about 6.5 to about 14, about 7 to about 13.5, about 7.5 to about 13, about 8 to about 12.5, about 8.5 to about 12, about 9 to about 11.5, about 9.5 to about 11, about 10 to about 10.5, about 2.5 to about 13, about 0.5 to about 5, or about 5 to about 20, grams. It is contemplated that the entire conditioning composition may also have a weight as described above or even up to about 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30, grams. However, it is also contemplated that smaller or larger core particles can be used. In various non-limiting embodiments, it is contemplated that all values and ranges of values, both whole and fractional, between and including the aforementioned values, can be utilized herein.

In one embodiment, the core particle (22) or composition is in the form of granules. The core particle (22) can be small fractionated objects formed from solid particles aggregated together, of variable shapes and sizes. They may be regular or irregular in shape. They may in particular have a spherical shape, a square shape, a rectangular shape, or an elongated shape such as rods. In particular, the core particle (22) can be in the form of small fractionated objects, which can have varied shapes, generally a regular shape and typically a spherical shape or well-calibrated (uniform) spherical shape. In one embodiment, spherical particles are quite particularly preferred. It is contemplated that instead of a core particle, the powder is free-flowing.

The (average) size of the particles of the core particle or composition is not particularly limited and can be from about 1 to about 5000 μm, from about 50 to about 5000 μm, from about 100 to about 3500 μm, or from about 200 to about 3000 μm. In other embodiments, the particles have an (average) size of about 1, 2, 3, 4, 5 . . . 10 . . . 50, 100, 150, 200, 250, 300, 350, 400, 450, 500 . . . up to about 5000, μm. Similarly, the D10, D50, and D90 values for the particles may be any of the above and may be alternatively described as Dn10, Dv10, Dn50, Dv50, Dn90, or Dv90. The size of the particles can be determined by manual sieving or via a mechanical calibrator, and also by laser particle size analysis, using for example the Malvern Mastersizer 3000. In various non-limiting embodiments, it is contemplated that all values and ranges of values, both whole and fractional, between and including the aforementioned values, can be utilized herein.

Starch can be used in pressed powder tablets because it is compressible, inert, fee flowing, cost effective and exhibits good disintegration properties. Water can be incorporated into dry powder starches to bind the starches together through interactions such as hydrogen bonding. The addition of water encourages stronger interaction between the starch hydroxyl groups which helps give strength and hardness to the final pressed powders.

The instant composition and/or core particle may include a liquid, such as water, or may be free of a liquid, such as water. Other liquids may include additives, surfactants, etc. In various embodiments, the liquid is present in an amount of from about 0 to about 30, about 1 to about 30, about 5 to about 25, about 10 to about 20, about 10 to about 15, about 15 to about 20, weight percent based on a total weight of the core particle and/or composition. In various other embodiments, the amount of liquid is from about 0 to about 25, about 5 to about 20, about 10 to about 15, about 5 to about 25, about 5 to about 15, about 5 to about 10, about 10 to about 25, about 10 to about 20, about 15 to about 25, about 15 to about 20, or about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, or 25, weight percent based on a total weight of the core particle and/or composition. In various non-limiting embodiments, it is contemplated that all values and ranges of values, both whole and fractional, between and including the aforementioned values, can be utilized herein.

In various embodiments, the core particle and/or composition may have a weight ratio of powder:liquid is from about 1:1 to about 1:3, about 1 to about 2.5, about 1 to about 2, about 1 to about 1.5, about 1.5 to about 3, about 1.5 to about 2.5, about 1.5 to about 2, about 2 to about 3, about 2 to about 2.5, or about 2.5 to about 3. Various examples are set forth in FIGS. 6-8 . In various non-limiting embodiments, it is contemplated that all values and ranges of values, both whole and fractional, between and including the aforementioned values, can be utilized herein.

Free of Talc:

The composition and/or core particle is typically free of talc. In various embodiments, the composition includes less than 5, 4, 3, 2, 1, 0.5, or 0.1, weight percent of talc based on a total weight of the core particle and/or conditioning composition. In other embodiments, the composition is completely free of talc. In various non-limiting embodiments, it is contemplated that all values and ranges of values, both whole and fractional, between and including the aforementioned values, can be utilized herein.

Starch:

As first introduced above, the composition and/or core particle includes tapioca starch, and optionally potato starch, and optionally corn starch. The starch, or combination of starches, are used to achieve desired benefits as shown, for example, in FIGS. 9 and 11 . Natural starch is comprised of amylose which is linear and amylopectin which is branched. Starches from different sources contain different proportions of these components which contribute to different properties. Additionally, the source of the starch, e.g. corn, potato or tapioca leads to different starches having different particle shapes and sizes. These properties of various starches influence the end results of formulating with these raw materials. For example, in one embodiment, tapioca starch is not used alone because it becomes too compact and cannot be broken apart easily. Corn starch has irregular polyhedron shaped granules having a diameter of from about 5 to about 20 μm, as shown for example in FIG. 10 . Any starch known in the art can be used in combination with the tapioca starch. Similarly, the compositions described herein may be free of any one or more starches known in the art, apart from tapioca starch.

The composition and/or core particle may be free of rice starch. In various embodiments, the composition and/or core particle includes less than 5, 4, 3, 2, 1, 0.5, or 0.1, weight percent of a starch, such as rice starch, based on a total weight of the core particle and/or conditioning composition. In other embodiments, the composition and/or core particle is completely free of a starch, such as starch, so long as this starch is not tapioca starch. It is also contemplated that the composition and/or core particle may be free of potato starch and/or corn starch, e.g. in the weight amounts described above or may be totally free of potato starch and/or rice starch. In various non-limiting embodiments, it is contemplated that all values and ranges of values, both whole and fractional, between and including the aforementioned values, can be utilized herein.

In various embodiments, tapioca starch can be used in combination with potato and/or corn starch to provide strength to the composition as a pressed powder, as well as a gentle crumble and soft feel. Potato starch has one of the largest particle sizes of native starches averaging from about 18 to about 60 μm. The larger particles are spherical and smooth in shape, giving a very silky skin feel due to the ball bearing effect. Tapioca starch has irregular round spheres with smaller particle sizes of from about 5 to about 25 μm. The combination of the large and smaller particles, which may include corn starch, allows for close packing and interaction during compression. This provides the strength to a pressed powder to hold up during packaging, shipping and consumer use.

In various embodiments, the tapioca starch has a moisture level of less than about 15 wt. %. The potato starch may have a maximum moisture level of about 205 mg water/g of starch. Tapioca starch is typically obtained from the roots of Manihot esculenta and includes primarily amylose and amylopectin. Potato starch is a polysaccharide obtained from the potato and may be alternatively described as solanum tuberosum starch.

In various embodiments, the tapioca starch is present in an amount of from at least about 1, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, or up to about 99, weight percent based on a total weight percent of the core particle or composition. In other embodiments, the tapioca starch is present in an amount of from about 10 to about 40, about 15 to about 35, about 20 to about 30, about 25 to about 30, about 25 to about 35, or about 30 to about 40, weight percent based on a total weight percent of the core particle or composition. In still other embodiments, the tapioca starch is present in an amount of from about 30 to about 70, about 30 to about 65, about 30 to about 60, or about 30 to about 55, weight percent based on a total weight percent of the core particle or composition. In various non-limiting embodiments, it is contemplated that all values and ranges of values, both whole and fractional, between and including the aforementioned values, can be utilized herein.

In various embodiments, the potato starch is present in an amount of from at least about 1, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, or up to about 99, weight percent based on a total weight percent of the core particle or composition. In other embodiments, the potato starch is present in an amount of from about 10 to about 40, about 15 to about 35, about 20 to about 30, about 25 to about 30, about 25 to about 35, or about 30 to about 40, weight percent based on a total weight percent of the core particle or composition. In various embodiments, the potato starch is present in an amount of from about 1 to about 30, about 5 to about 25, about 10 to about 20, about 15 to about 20, about 1 to about 10, about 1 to about 5, about 5 to about 10, or about 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10, weight percent based on a total weight percent of the core particle or composition. In various non-limiting embodiments, it is contemplated that all values and ranges of values, both whole and fractional, between and including the aforementioned values, can be utilized herein.

In various embodiments, the corn starch is present in an amount of from at least about 1, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, or up to about 99, weight percent based on a total weight percent of the core particle or composition. In other embodiments, the corn starch is present in an amount of from about 10 to about 40, about 15 to about 35, about 20 to about 30, about 25 to about 30, about 25 to about 35, or about 30 to about 40, weight percent based on a total weight percent of the core particle or composition. In various embodiments, the corn starch is present in an amount of from about 1 to about 10, about 1 to about 5, about 5 to about 10, or about 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10, weight percent based on a total weight of the core particle or composition. In various non-limiting embodiments, it is contemplated that all values and ranges of values, both whole and fractional, between and including the aforementioned values, can be utilized herein.

In various embodiments, the total amount of tapioca starch, potato starch, and corn starch is from about 10 to about 80 weight percent based on a total weight of the core particle or composition.

Coating Disposed About at Least a Portion of the Core Particle:

Relative to the encapsulated composition, the coating (24) typically improves the hardness and durability (e.g. strength and rigidity) of the encapsulated composition (20) while simultaneously reducing friability during transport and use. This reduces shipping and handling costs, preserves the integrity of the encapsulated composition when sold, and minimizes costs associated with replacement of a prematurely fractured product.

The coating may be, include, consist essentially of, or consist of, one or more of the compounds described below. For example, the coating (24) may be, include, consist essentially of, or consist of, one or more compounds chosen from cellulose polymers, anionic or cationic polymers, vinyl polymers, natural polymers, polysaccharides, copolymers thereof, and combinations thereof. In other embodiments, the coating (24) may be, include, consist essentially of, or consist of, one or more of cellulose based polymers such as hydroxypropyl methyl cellulose (HPMC), hydroxypropyl cellulose (HPC), ethyl cellulose (EC), natural anionic or cationic polymers such as sodium polyitaconate and chitosan (70-95% deacetylated), vinyls, such as polyvinyl alcohol, and acrylate polymers or copolymers, natural derivatives, such as shellac or alginates, polysaccharides, and/or combinations thereof.

Moreover, in other various non-limiting embodiments, it is contemplated that all values and ranges of values, both whole and fractional, between and including the aforementioned values, for any one or more of the aforementioned components, and all combinations thereof, can be utilized herein.

It is contemplated that all weights described herein may be on the basis of a core particle, a powder, an encapsulated particle, or a composition as a whole. It is contemplated that any one or more weight percents described in this disclosure may be alternatively described as weight percent actives. Relative to all descriptions of liquid and/or water herein, each amount may be alternatively described as a “total amount.” Typically, the terminology “total amount” refers to a total amount of liquid and/or water present in the composition from all components, i.e., not simply liquid and/or water added independently from, for example, the surfactant component. An independent source of liquid or water, such as DI water, may be used to dilute the composition. This liquid or water may be independent from any liquid and/or water present in the composition as originating from one or more components. In other words, the composition can include liquids and/or water originating from the components themselves. However, to further dilute the composition, the independent liquid and/or water source may be used.

In still other embodiments, the composition may be described as a waterless hair care, styling and treatment cosmetic composition. The composition may be described as a mixed powder that includes about 0-20% liquid that may be water, oils and bonding ingredients. The composition may be a free flowing powder or pressed powder of different shapes and sizes. The composition may be activated in situ in contact with water representing maximum freshness and efficacy versus liquid products. Furthermore, the composition may have better stability and better efficacy due to higher stability of functional ingredients in the composition powder form. Vitamins, oils, proteins, etc. tend to be preserved in the powder form where these ingredients will have limited efficacy in the liquid form with time. The composition requires minimum space, is sustainable (e.g. does not require plastic packaging), and produces minimum waste (e.g. in individual solid doses). The composition can include a mixture of starches including corn, potato, tapioca, barley, rice as the primary carrier ingredients, primary anionic or nonionic surfactants, secondary surfactants, anti-foam agents, gums, thickeners, conditioning agents, oils, silicone (or may be silicone free), fatty alcohols, quats, humectants, pH adjusters, sun blockers, colorants and preservatives.
